Hi,
If you're interested I just finished a PCB to mount an ACSI2STM inside Mega STE using the internal DMA connector.
The KiCAD project is available here : https://github.com/olivierjan/ACSI2STM-MSTE

Re: Mega STE Internal ACSI2STM
That looks very much like the holy grail. Nice job.
Re: Mega STE Internal ACSI2STM
This looks very neat, Olivier!
Got any pictures of it in situ?

He got a whole build thread on AtariAge.

Ah, yes! Excellent work, Olivier. Perfect for the job.

Re: Mega STE Internal ACSI2STM
I received a few new Bluepill yesterday and I would like to test the stability of the interface.
Is there any TOS software to test the hard disk? It clearly works, reads, writes but I would like to run some tests over a few hours to make sure it’s stable and there’s no corruption.
